WASTE MECHANISM.

Application filed May 5, 1920. Serial 1\T'o. 378,995.

To a-ZZ y11i/rom t may cof/tecra.'

Be it known that l, EDWARD F. .hin- DECKEN, a citizen of the United States, residing` at lsiilwaukee, in the county oi'l liiilwaukee and State et vlflfisconsin, have invented certain new and usetul ln'iprovements in lWaste Mechanism, et which the iollowingl is a speciiication. reference being had to the accompanying drawing, forming a part thereoi'.

This invention'relates to waste mechanism i'or bath tubs and similar receptacles and the object of the invention is to improve the construction and operation oi' waste mechanism in the manner to be hereinafter described and claimed.

Referring to the drawingsv which accompany this specication and torni a part hereof, which drawings illustrate an embodiment of this invention, and on which drawings the same reference characters are used to designate the same parts in each ot the views, Fig. 1 is a vertical section of the waste mechanism, parts being shown in elevation; and Fig. 2 is a vertical section taken on the line 2-2 on F ig. 1, looking in the direction indicated by the arrows.

Referring to the drawings, the reference numeral 1 designates a bath tub, or liquid receptacle, which is provided with an outlet aperture 2 and an overliow aperture 3. A pipe connection 41, which is provided with a 'flange 5, is screwed. tinto the elbow 6 and a parking 7 makes a fluid tight joint, The

elbow G is connected with the stand pipe 8- in line with a tubular valve 9. The valve 9 has an upper, circumferential valve 'face 1() and a lower, circumferential valve lf'ace 11. The upper valve tace 1 0 projects beyond the body ot the valve and the lower valve face 11 is arranged within the circumference of the body oi the valve so that the valve may be readily assembled or disassembled. Inwardly projecting valve seats 12 and 13 are provided for the valve faces 1() and 11. lt will be readily seen from an inspection of Fig. 1. oi the drawings that, with this construction, when the valve 9 is closed, iiuid cannot escape from the receptacle 1 either up or down past the valve 9 while Huid overiiowing is free to pass through the valve 9. The valve body 14 isV preferably provided with a guide or steady flange or rib 15 which is located opposite the elbow 6 to guard i sticking and wear.

against displacement lor binding ot the valve 9 when the valve is partly opened' and Vfluid is running to waste through the elbow 6.

`The tubular body 16 ot thevalve 9 makes a' substantially closelit within the valve seat 12 to prevent fluid from rising past the valve 9 and fouling the vinterior `oi the stand pipe 8 and. the parts at the lower end thereof. This construction makes the mechanism sanitary and reliable. vThe ,valve seat 12 serves as a scraper to remove deposits on the exterior of the valve 9 and, as it is very short vertically, there is no opportunity for soap, for example, to work in between the valve and the seat and produce corrosion,

The valve 9 can be raised and lowered in any suitable manner. The drawings illustrate a knob 17 connected with the valve and studsl 18 and 19 projecting into inclined grooves in a member at the top of the stand pipe so that the valve can be opened and closed and can be held open in a common and well-known manner.

One of the difculties heretofore encountered in installing bath tub wastes has been due to the diierent inclinations of the ends o bath tubs in which the overflow apertures were located. I overcome the difficulty by! using an overow pipe 2O which projects into a nipple 21 on the stand pipe v8 and which is made smaller than the interior ol? the nipple so that it can be turned out of direct line with the nipple. A Y makes a fluid tight joint and the 'j follower 23 is bored larger' than the pipe 20. The pipe 20 is provided with a flange 24 to seat against the bath tub, and the joint is made tight by a packing 25. A rod 26 is screwthreaded at both ends and is screwed into a uut 27 passes through the grating 28 and is provided with a nut 29 on its end bearing against the grating. `The nut 27 is movable within the nipple 21 so that the rod 26 can assume different angles. The drawings illustrate the .nut y27 as pivoted on pivot screws 30 and 31, which are screwed into the nipple 21 and engage with recesses inthe nut 27.

The advantages of the invention arel of great importance from practical and sanitary standpoints. One standard overflow cured to bath tubs, or receptacles, the in- A packing 22 clinations of the ends of which vary. The foul Waste Water doesI not reach the interior of the stand pipe and bei'oul the same, and all of the surfaces exposed to the foul Waste fluid are in direct line With the flow ofthe-fluid to be flushed by the flow of the uid.

The valve body 14; is provided Withthe Waste inlet 32 and the stand pipe 8 is provided with the overflow inlet 33 above' the Waste inlet 32. The stand pipe 8 and the "Waste `pipes-34 and are illustrated bythe drawings as connected with the valve lbody 14 by means of slip joint connections to illustrate a practical vand convenient method of making pipe connections. i,

`What I claim is: Y

l. In'a Waste`mechanism, the combination with a valve body provided with a Waste inlet and inwardly "projecting valve seats 'above and belowk the Waste inlet, of a tubular valve provided With upper and lower valve faces to coact with said valve seats.

2. In Waste mechanism, the combination with a valve body provided With a Waste inlet, inwardly' projecting` valve seats above and below the Waste inlet and a gnideopposite the Waste inlet, of a tubular valve provided with upper and'lovver valve faces and a body to be positioned by said guide.

3. In'waste mechanism, the combination with a valve body provided With a Waste inlet and inwardly projecting valve `seats above and below the Waste inlet,'of a tubular valve provided With upper and lower valve faces to coact With'said valve seats and also provided With a body part, the upper valve seat closely fitting the 'body part of the valve.

In Witness whereof I hereto ai'HX iny signature.

EDWARD F, NIEDECKEN.
